SBCGlobal.net mail login is an internet domain. It might be the user's email address or the email address of someone the user knows. SBCGlobal email addresses were supplied by SBC Communications, formerly known as Southwestern Bell Corporation. SBCglobal mail login addresses generally comprise a username and a domain name. Southwestern Bell Corporation was one of the seven "Baby Bell" companies formed when AT&T split off its regional telephone company components during antitrust litigation in the 1980s. Even though the accounts are now administered by AT&T, some consumers who had accounts with SBC Global Internet service providers before SBC's merger with AT&T still have accounts with the domain sbcglobal.net.
